Ethyl Glucuronide (EtG) is a unique biological metabolite that is formed in the body after the consumption of ethanol, typically from drinking alcoholic beverages. Reported to be detectable in urine typically from 8-80 hours after ingestion, and 2-36 hours in blood EtG is detectable over a period roughly 5-6 times longer than traditional urine ethanol testing Detectable in oral fluid only a few hours longer than ethanol* EtG has also been isolated in hair follicles *G.Heiseth, B.

Best Answer: EtG is a direct metabolite of beverage alcohol (ethanol). Its presence in urine may be used to detect recent alcohol consumption, even after ethanol is no longer measurable. The presence of EtG in urine is a definitive indicator that alcohol was ingested.EtG is detectable in urine for up to 80 hours after the elimination of alcohol.EtG is only evident when alcohol is consumed and is not produced as a result of fermentation.
